Specification of Letters Patent.

Application filed. May 5, 1913. Serial No. 765,480.

Patented Nov.18,19l3.

To all whom it may concem Be it known that I, GEORGE Flsonnurr, acitizen of the United States of America,

and a resident of Chicago, in the county of (look, State of Illinois,have invented certain new and useful Improvements in Folding Beds, ofwhich the following is a specification. I I

This invention relates to that type of foldmg beds i'nlwhich a series-ofbed sections are pivoted together and to the main frame, and are adaptedto unfold outwardly from the back portion of the main frame, so thatwhat is'terrn'ed the foot of the bed w1ll be 1 5 farthest removed fromsaid main frame.

And the object of the present improvement is tojprovidc a sim lo andefficient structural formation an combination of parts,

uwith' which the-folding and the unfolding operation of the bed partscan be readily and conveniently effected, and in which the bedsections-in their unfolded condition are substantially supported againstsagging in ec'tualuse, all as will hereinafter more fully zojap earl nthe accompanying drawings :Figure 1,;15 a side elevation, with an armportion of the. main frame removed and with the back' portion of saidframe in segtion, illustrating a bed members of the present constructionin their folded condition. Fig.2, is'a similar fragmentary sideelevation, illus trating said-bed members in a partly unfoldedcondition. Fig. 3 is a detail'transverse section on line mw,.Fig. 1.,Fig. 4, is a side elewi-tion similar to,,Fig. 1, illustrating the 'bedmembei's in their unfolded condition.

Fig. 5, is a detail horizontal section, on line.

wm, Fig. 4. F ig,'6, is a detailperspectiye view of the. means for.locking the front bed member in place, when the .bedmembers are in theirfolded condition. Fig. 7, is a fragmentary horizontal section on line a2-iv Fig-4.1 :Fig. ..8, is adetail perspective view of the back plate-orboard of the main frame, and illustrating the arrangement of pockets onthe same. I i

Similar .reference numerals indicate like partsiin the several: views.

Referring to the drawings, 1 represents the main frame of thepres'entconstruction,

preferably a skeleton metal structure, and

made readily portable by supporting cas- -ter s 2, as"usual. Said frame1, has fixed attachment inside of and at thelower portions of the endarms 3, and the back 4 of a sofa-bed. as shown. a

5 is the reversible seat member, pivoted to the front of the main frame1 by upright radius links 6,,and adapted to swing from the scat formingposition illustrated in Fig. 1, into the inverted position illustratedin Fig. 4:. In its preferred construction shown in thedrawings,theabo've described swinging movement of the seat member 5 issupplemented by a horizontal movement'ofthe same, with the radius links6 adapted to govern said horizontal movement. J

7 is a stop? or hook carried by a radius link 6, and adapted forengagement with the main frame 1, to limit the outward swing of saidradius link.

8 is a supporting foot secured to the reversible seat member 5, at theside opposite i to the attachment of the radius links 6, aforesaid, andadapted to support said scat member when the parts are in the unfoldedcondition shown in Fig. 4. 1

9l are supporting ledges or rails secured to the inside of the end arms3, aforesaid, and upon which ledges at the ends of the seat member 5,rests, when said seat member is in its seat forming positionillustratedin Figs. 1 and 3.

10 is the back member of the sofa-bed,

pivoted at top to the connecting rail 3 0fcation immediately beneath theseat member 5 as shown in Fig. 1, while in an unfolded oosition said bedmember has alo cation above and to the front of the seat 7 member 5,asshownin Fig. 4, and in its. shifting from one position to theothersaid bed member 11, has a walk over movement past said seat member5, due to the radius links 12, aforesaid.

13 is a leg secured to the front end of bed clothing.

the front bed section 11 for the support of the same in an unfoldedposition of the bed Darts.

14 is a tension spring attached at one end to the seat member 5 and atthe other end to one of the radius links 12 at a point removed from thepivotal connection of said links to the front bed member 11. Said springis inactive except in the initial unfolding and in the final foldingmovement of the bed parts, and in the one case is adapted to assist inthe initial unfolding movement, and in the other case to yieldinglyresist the final folding together of the seat member 5 and front bedmember 11.

15 is the central bed member or section having its front end connectedto the front bed member 11 by anarrow intermediate bed section in anyordinary pivoted manner. The rear end of said central bed mem.- ber 15,is pivoted directly to the rear bed member 19 hereinafter described."With the described construction, and when the said bed members are inthe folded position illustrated in Fig. 1, an interior cavityis-provided for holding the mattress and, other 17 is a knee piece fixedon thecentral bed member 15, and adapted to ride over and rest upon anabutment or projection 18 on the seat member 5, in the unfolded positionof the bed parts, and support said central bed member 1.5 against 'atendency to sag in actual use.

19 is the rear bed member pivoted at its front end to the central bedmember 15, above described, and at' its rear end to the upper end of anupright radius link 20, which in turn is pivoted at its lower end to themain frame 1.

21 is a bracket carried by the radius bar 20, aforesaid, and 22 is atension spring connected at one end to the outer end of said bracket andat its other end to the main frame 1. The function of said spring beingto assist in a rear movement of the radius link 20 and its accessories,and to yieldingl'y resist a forward movement of the same.

23 is an angle bracket secured to the rear end-of the rear bed member19, and adapted in the folded position of the bed members, illustratedin Fig. 1, to constitute onemember of the hereinafter described lockingmechanism by which said bedmembcrs are locked in said folded position.Iii-the unfolded position of the bed members, illus trated in Fig. 4,the said angle bracket 23 is adapted to form an abutment or stop lug forthe hinged back 10 of the sofa-bed to retain-the back in properpositionb In the folded position of 'the bed parts, thepropr position,of said baclr'lO, 1S maintained an abutment or stop 21* carriedby theseat member ,5, asillustrated more particularly in Fig. 1. s

25 is a catch piece secured to the before described supporting leg 13,of the front bed member 11, and adapted in a folded position of the bedparts as shown in Fig.

1, to catch under the free end of the angle bracket 23, aforesaid, andlock the bed parts in the vsaid folded position. In effecting a.disengagement of the catch piece 25 and bracket 23 previous to anunfolding movement of the bed parts, the operator pulls the leg 13forwardto carry the catch piece 25 out of the described engagement.

26 is the front board of the base portion of .the main frame, carried bythe radius links 6, of the seat member 5, and connect edto said seatmember by a flexible Web 27, to provide a closure for thevlower front ofthe sofa-bed and conceal the mechanism as ,Well as the articles in theinterior of the sofa bed. 7

28 are pockets. attached to the back board 1, aforesaid for containingin a convenient and accessible manner, the night clothes,

etc., of the user. y

The operation of the present improved construction is as follows :Withthe parts in the folded condition illustrated -=in Fig. 1, the operatorinitially swings the sofa back 10, up into the position shown in dottedlines in said Fig. 1. operator grasps the leg 13 and first springs thesame slightly forward to disengage the catch 25 from its lockingengagement with the angle bracket 23, after which by a forward pullingaction on said leg, the bed members are automatically unfolded into theposition illustrated in Fig. 4. During such unfolding operation thefront bed member 11 has a walk over movement with relation to the seatmember 5, due to the radius ,links 12. During suchoutward After this theL ioo movement of the front bed member 11, due I to the pull of theoperator, the other pivotallyconnected bed members are drawn outseatmember 5, to provide a support'for 17of the central bed member 15 ridesinto engagement with the abutment 18, of the the central portion of thebed member against asagging tendency in actual use.

Afte'rthe above described unfolding 'oper-' ation, the-sofa backlO islowered into, 1
